3ac1a6b288 Handle receiving in the beginning without clock gracefully 
We'll only have a clock once the source element is actually in Playing.

5e5007091e Always return 1 frame of latency except for timecode mode 
This allows for some slack when receiving, as up to 1 frame difference between
receive times can easily happen because of capturing alone.

And return 5 frames maximum latency as that is the size of our internal
queue.

fa9f788190 Improve type-safety a bit by making the Receiver generic over the stream type 2019-07-19 11:34:20 +03:00

33370e42ad Collect observations for the timestamp/receive time mappings and smoothen them 
This allows keeping audio/video more in sync with how the sender was
sending it, while also handling network jitter and clock drift in a
reasonable way.

66d4fd1d90 Move connecting and capturing to separate threads 
This ensures that we'll be able to capture every frame even if
downstream of the source is blocking for a moment, and also allows us to
make all operations cancellable.

f27c2507c5 Refactor huge create() functions into multiple smaller functions 
And don't hold any mutexes when unnecessary, especially not while trying
to receive a frame.

34858762f7 Consolidate element properties 
stream-name is called ndi-name everywhere in the NDI SDK and documentation
ip is called ip-address everywhere

Rename loss-threshold to timeout and change it to be in milliseconds
instead of iterations.

Add connect-timeout for timeout during connection

Add bandwidth and receiver-ndi-name properties, and initialize the
latter with a reasonable default value.

5022ff412c Fix caps negotiation 
We can't just fixate to any close to what we receive right now but only
support exactly the caps we receive. So check the format of each frame
and negotiate exactly those caps as needed when receiving frames.

Also re-negotiate if the caps are ever changing.

2ad413773e Take the current running time as PTS for now and clean up timestamp/duration calculations 
We might want to take the timestamp provided by the NDI SDK at a later
time but this needs to be done correctly.

This also fixes various memory unsafety issues.

And add lots of FIXME comments for code that is currently wrong.

a0c918de71 Never send an empty buffer but simply retry 
Sending an empty buffer will cause downstream to fail as it has the
wrong size.

I.e. based on the framerate for video and based on the buffer size,
sample size and sample rate for raw audio.

b41d5839d4 Always free video frames with NDIlib_recv_free_video_v2() after last use 
And not potentially before or not at all.

7b8070c55d Use slice::from_raw_parts instead of Vec::from_raw_parts 
The latter must only be called on memory that was allocated by Rust for
a Vec and will cause crashes depending on the platform otherwise.

Also it would free the memory as if a Vec was allocated, which would
free memory that we don't own to begin with.
